Fox-ESS is one of the fastest-growing battery and inverter brands in the UK. The H1 and H3 hybrid inverters paired with the EP5 modular battery range deliver Tesla-level capability at value pricing — a sweet spot for many Midlands installs.
✓EP5 modular battery (5.2kWh blocks, stackable to 15.6kWh)
✓10-year battery warranty
✓Strong app and dashboard
✓Approved installer programme — we are accredited
Fox-ESS is our go-to value option, sitting just below Tesla Powerwall (premium) on price while matching much of its capability. The hardware is excellent — LiFePO4 batteries with strong cycle life, slick aluminium-cased inverters, and a particularly good integrated app for monitoring and tariff arbitrage.
We install Fox-ESS H1/H3 + EP5 combinations regularly, particularly for customers wanting modular battery capacity (start with 5.2kWh, add more as needs grow) and good EV-charger integration.
Upgrade any package to the Fox ESS EP12 (11.52kWh) for £995.
